They’ve made some changes for the hamachi unattended computers. If you don’t have a payed subscription and you closed your remote desktop connection session, your hamachi will disconnect too. As I use it in combination with a rasberry pi, this is really irritating! But we have a workaround!

So as a workaround you can log off your RDP without closing the session creating a shourtcut in your desktop directed to “%windir%\System32\tscon.exe RDP-Tcp#0 /dest:console” and run as administrator. This will log you off and leave the session open. Just saying.
